为了定量油菜主茎叶片形态参数与生物量间的关系,本研究基于2011—2012年和2012—2013年不同品种、移栽密度及施肥水平油菜田间试验,通过观测不同品种和处理油菜叶片长、最大叶宽和叶柄长等形态参数,并分析了上述参数与叶片生物量的关系,构建了基于生物量的油菜叶长、最大叶宽和叶柄长模型。结果表明,在全生育期,不同品种和处理下油菜主茎叶长和最大叶宽均与叶片生物量的平方根成正比,而叶柄长与叶长成正比。所建模型利用截距为0的线性函数描述叶长和最大叶宽随生物量平方根的变化,用直线式描述叶柄长随叶长的变化。经独立试验资料检验,除宁油16叶柄长模型误差较大外,所建模型对其余形态参数均具有较好预测性,为通过生物量将油菜生长模型与形态结构模型结合提供了机理性较强的方法,为建立油菜功能-结构模型奠定了基础。

To quantify the relationships between main stem leaf morphological parameters for rapeseed and the corresponding leaf biomass, we conducted field experiments on varieties, transplanting densities, and fertilizer in 2011 to 2012, and 2012 to 2013 seasons. The biomass-based leaf morphological parameter models for rapeseed on main stem were constructed through observing leaf length, maximum leaf width, and leaf petiole length under various treatments, and analyzing the relationships between leaf morphological parameters and the corresponding leaf biomass. Because both of the leaf length and leaf width were positively proportional to the square root of the corresponding leaf biomass, meanwhile the leaf petiole length was positively proportional to the corresponding leaf length, the changes in the leaf length, the maximum leaf width, and the leaf petiole length with the changed of square root of the corresponding leaf biomass for different treatments could be described with linear function. The bio-mass-based leaf morphological parameter models were validated using independent experiment data, and the results showed that the model revealed satisfactory predictions of leaf length, leaf width, and leaf petiole length, except the simulation for leaf petiole length of Ningyou 16. The research provides a mechanistic method for linking the rapeseed growth model with the morphological model using organ biomass, and lays a foundation for the establishment of functional-structural plant models of rapeseed.
